    • The present invention relates to a fibre sheet material and method of laying up fibre sheet material to manufacture wind turbine blades. The invention further comprises a blade manufactured by the method as well as a use of such a blade. One aspect relates to an oblong fibre sheet material(26)for wind turbine blades, where a surface layer (14) is having a width, which in the lateral direction is broader than a lateral, unidirectional layer (10), and lengthwise side faces of at least the surface layer is provided with a thinning of a thickness of the layer to obtain favourable joints. Another aspect concerns manufacturing a wind turbine blade shell comprising laying fibre sheet (26) materials in a blade mould (20), where the sheet materials lengthwise are positioned in a direction corresponding to a chordwise direction of a turbine blade direction of the mould and overlapping in a spanwise direction. The effect obtained is a significant reduction in the amount of waste material compared to laying fibre sheets in the spanwise direction.
    • 本发明涉及纤维片材和铺设纤维片材以制造风力涡轮机叶片的方法。 本发明还包括由该方法制造的叶片以及这种叶片的使用。 一个方面涉及一种用于风力涡轮机叶片的椭圆形纤维片材料(26),其中表面层(14)具有在横向方向上比横向单向层(10)更宽的宽度,并且纵向侧面 至少表面层的厚度变薄以获得良好的接合。 另一方面涉及制造风力涡轮机叶片壳体,该风力涡轮机叶片壳体包括将纤维片(26)材料铺设在叶片模具(20)中,其中片材纵向定位在与模具的涡轮叶片方向的弦向相对应的方向上, 沿翼展方向。 与沿翼展方向铺设纤维板相比,所获得的效果是废料量显着减少。
